Erm. But there *isn't* a problem.

The only `problem', is that it's not obvious what you ought to be
doing when you're working with Essential packages. As was seen when
Torsten applied my patch to bash and royally screwed it, because /bin/sh
disappeared between bash being unpacked and configured.

This doesn't imply any changes to the archive at all, beyond fixing bash.

The details and stuff are in the bug report against -policy, fwiw.

Cheers,
aj
